Legio X Fretensis

Legio X Fretensis ("Tenth legion of the Strait") was a legion of the Imperial Roman army. It was founded by the young Gaius Octavius (later to become Augustus Caesar) in 41/40 BC to fight during the period of civil war that started the dissolution of the Roman Republic. X Fretensis is then recorded to have existed at least until the 410s.

X Fretensis symbols were the bull — the holy animal of the goddess Venus (mythical ancestor of the gensJulia) — a ship (probably a reference to the Battles of Naulochus and/or Actium), the god Neptune, and a boar. The symbol of Taurus may also mean that it was organized between 20 April and 20 May.

In 31 BC, it fought in the Battle of Actium against Mark Antony. Although Actium was a battle at sea, the legion was able to board enemy ships that had been hooked close by means of an iron grapnel known as the Corvus.[2] Its key participation in this battle is probably the reason that the legion also used a trireme as one of its symbols. Actium marked the end of the civil war and the rise to power of Octavian, who was proclaimed Augustus some years later.

It uncertain when the legion was redeployed to Macedonia. An inscription found in the valley of the Strymon river attests that a group of soldiers from the unit had built a bridge.[3] While stationed in that province, it fought battles with the Sarmatae who attacked the province in 16 BC. Not much later, Legio X Fretensis went to Syria.[4] An inscription in the temple of Bel in Palmyra dated AD 14-19, signed by the commander of the legion, was dedicated to members of the emperor's family.[5] This has led experts to believe X Fretensis took part in Germanicus' campaign in the East, as well that the legion was stationed at Zeugma to secure the frontier with Parthia.[4]

In 66, the X Fretensis and V Macedonica went to Alexandria for an invasion of Ethiopia planned by Nero. However, the two legions were needed in Judaea to suppress a revolt. After spending the winter in Ptolemais Ace (modern Acre, Israel), X Fretensis and V Macedonica relocated in the coastal city of Caesarea Maritima (67/68). This was due to the large number of legions being mobilized in Ptolemais, under Marcus Ulpius Traianus, future governor of Syria and father of the emperor Trajan. During that same winter, the Caesarea camp of Xth and Vth hosted Vespasian, who was forced to go to Rome the following year, where he seized power. Vespasian's son Titus finished the suppression of the revolt.

By 70, the rebellion in all of Judaea had been crushed, except for Jerusalem and a few fortresses, including Masada. In that year X Fretensis, in conjunction with V Macedonica, XII Fulminata, and XV Apollinaris, began the siege of Jerusalem, stronghold of the rebellion. The Xth camped on the Mount of Olives. During the siege, Legio X gained fame in the effective use of their various war machines. It was noted that they were able to hurl stones that weighted a talent (about 25 kg) a distance of two furlongs (400 m) or further. The projectiles of their ballistae caused heavy damage to the ramparts. According to Josephus (vol. III of his history of the Judaean war), Larcius Lepidus was the commanding officer of the X Legion. The siege of Jerusalem lasted five months and the besieged population experienced all the terrible rigors of starvation. Finally, the combined assaults of the legions succeeded in taking the city, which was then subjected to destruction.

During the spring of 71, Titus set sail for Rome. A new military governor was then appointed from Rome, Lucilius Bassus, whose assigned task was to undertake the "mopping-up" operations in Judaea. Naturally, he used X Fretensis to oppose the few remaining fortresses that still resisted. As part of this, X Fretensis took Herodium, and then crossed the Jordan to capture the fortress of Machaerus on the shore of the Dead Sea. Due to illness, Bassus did not live to complete his mission. Lucius Flavius Silva replaced him, and moved against the last Jewish stronghold, Masada, probably in the autumn of 72. He used Legio X, auxiliary troops, and thousands of Jewish prisoners. After his orders for surrender were rejected, Silva established several base camps and a wall of circumvallation completely around the fortress. When the Romans finally broke through the walls of this citadel, they discovered that the Jewish defenders had chosen death with a mass suicide.

After the conclusion of the Jewish revolt, Legio X was garrisoned at Jerusalem. Their main camp was positioned on the Western Hill, located in the southern half of what is now the Old City, which had been levelled of all former buildings. The camp of the Tenth was built using the surviving portions of the walls of Herod's royal palace, demolished by order of Titus. Once the Romans rebuilt parts of the destroyed city as the pagan city of Aelia Capitolina, the camp found itself at the end of the cardo maximus.[6]

At the time, Legio X was the sole legion assigned to maintain the peace in Judaea, and was directly under the command of the governor of the province, who was also legatus of the legion.[7] This combination of offices made this posting important, and several of the men assigned to it had previous experience commanding a legion.[8] However, when a second legion was assigned to Judaea, and the province promoted to consular status, the political status of legate of this legion declined; as Dabrowa observes, "he was subordinate to the governor of Judaea just like the commander of the second legion.[9]

A possible cause for the revolt was the decision of Emperor Hadrian to build a Pagan temple to Jupiter in Jerusalem. Simon Bar Kokhba started the revolt and inflicted massive casualties on the Romans. The war ended when the Roman army — including Fretensis and Danubian troops under the command of Sextus Julius Severus — reconquered the entire territory and successfully besieged the last Jewish stronghold, the fortress of Betar. Legio X Fretensis sustained heavy casualties in the course of the revolt.[10]

As a consequence of the unrest in the region, Fretensis was supported by several other legions, of which the Legio VI Ferrata was stationed at a camp which became known as Lejjun (from "legion").

A vexillation, or detachment, of X Fretensis along with other troops stationed in eastern provinces, fought in the Marcomannic campaign of Marcus Aurelius. However, when this vexillation arrived or what part it played in the campaign is not known.[11]

Under Gallienus (r. 253–268), another vexillation of Fretensis was drawn to fight in the war against the Gallic Empire. However, that unit defected to the other side.[12]

The legion moved to Aila (close to modern Aqaba),[13] probably during Diocletian's reforms (around 300), and is recorded as still camping there at the time of the compilation of the Notitia Dignitatum in the 390s, when it is reported serving under the Dux Palaestinae.[14]

Some fragments bearing the "L.X.F" mark of the Legio XFretensis are present at the Tower of David in Jerusalem. Roman Law required all pottery to bear the maker's stamp, and the Legion pottery works just to the West of Jerusalem were obviously no exception. A huge production of pottery bearing the marks of the Legio X Fretensis has been discovered in Jerusalem.[15]
The mark "LE X FR" was also used in the pottery of the Legion.[16]
